WPF: Command und CommandParameter für UserControl

Ich bin erstellen einer benutzerdefinierten UserControl und würde gerne mit dem UC eine Command genau wie die Button. Ich bin neu in WPF.

Dies ist, was ich bisher versucht habe ohne Glück:

WelcomeView.xaml

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="*"/>
        <RowDefinition Height="150"/>
    </Grid.RowDefinitions>

    <Controls:SignedButton Grid.Row="1" VerticalAlignment="Top" Width="245" Height="45" Foreground="#FFFFFF" 
                           LeftSign="+" Text="Add an account" TextSize="20" 
                           ButtonBackground="#3A5795" HoverBackground="#C41AD7" HoverOpacity="1"
                           Command="{x:Static Infrastructure:ApplicationCommands.NavigateCommand}" 
                           CommandParameter="{x:Type Views:AddAccountView}"/>
</Grid>

SignedButton.xaml.cs

public partial class SignedButton : UserControl
{

    public static DependencyProperty ButtonBackgroundProperty =
        DependencyProperty.Register("ButtonBackground", typeof (string), typeof (SignedButton));

    public static DependencyProperty CommandParameterProperty =
        DependencyProperty.Register("CommandParameter", typeof (object), typeof (SignedButton));

    public static DependencyProperty CommandProperty =
        DependencyProperty.Register("Command", typeof (ICommand), typeof (SignedButton));

    public static DependencyProperty HoverBackgroundProperty =
        DependencyProperty.Register("HoverBackground", typeof (string), typeof (SignedButton));

    public static DependencyProperty HoverOpacityProperty =
        DependencyProperty.Register("HoverOpacity", typeof (double), typeof (SignedButton));

    public static DependencyProperty LeftSignProperty =
        DependencyProperty.Register("LeftSign", typeof (string), typeof (SignedButton));

    public static DependencyProperty RightSignProperty =
        DependencyProperty.Register("RightSign", typeof (string), typeof (SignedButton));

    public static DependencyProperty TextProperty =
        DependencyProperty.Register("Text", typeof (string), typeof (SignedButton));

    public static DependencyProperty TextSizeProperty =
        DependencyProperty.Register("TextSize", typeof (double), typeof (SignedButton));

    public SignedButton()
    {
        InitializeComponent();
    }

    public string ButtonBackground
    {
        get { return (string) GetValue(ButtonBackgroundProperty); }
        set { SetValue(ButtonBackgroundProperty, value); }
    }

    public ICommand Command
    {
        get { return (ICommand) GetValue(CommandProperty); }
        set { SetValue(CommandProperty, value); }
    }

    public object CommandParameter
    {
        get { return GetValue(CommandParameterProperty); }
        set { SetValue(CommandParameterProperty, value); }
    }

    public string HoverBackground
    {
        get { return (string) GetValue(HoverBackgroundProperty); }
        set { SetValue(HoverBackgroundProperty, value); }
    }

    public double HoverOpacity
    {
        get { return (double) GetValue(HoverOpacityProperty); }
        set { SetValue(HoverOpacityProperty, value); }
    }

    public string LeftSign
    {
        get { return (string) GetValue(LeftSignProperty); }
        set { SetValue(LeftSignProperty, value); }
    }

    public string RightSign
    {
        get { return (string) GetValue(RightSignProperty); }
        set { SetValue(RightSignProperty, value); }
    }

    public string Text
    {
        get { return (string) GetValue(TextProperty); }
        set { SetValue(TextProperty, value); }
    }

    public double TextSize
    {
        get { return (double) GetValue(TextSizeProperty); }
        set { SetValue(TextSizeProperty, value); }
    }
}
